The rapid expansion of Zika virus (ZIKV), following the recent outbreaks of Chikungunya virus, overwhelmed the public health infrastructure in many countries and alarmed many in the scientific community. Aedes aegypti (L.) (Diptera: Culicidae) and Aedes albopictus (Skuse) (Diptera: Culicidae) have previously been incriminated as the vectors of these pathogens in addition to dengue virus. In our study, we challenged low generation Ae. aegypti (Chiapas, Mexico) and Ae. albopictus (North Carolina, Mississippi), with three strains of ZIKV, Puerto Rico (GenBank: KU501215), Honduras (GenBank: KX694534), and Miami (GenBank: MF988743)...

The blacklegged tick, Ixodes scapularis Say (Acari: Ixodidae), is an economically important tick that affects veterinary and public health, but it can be difficult to collect in Oklahoma. The primary goal of this research was to examine the diel activity of each species to help improve collection methods for future field research and test field-collected I. scapularis for endemic and nonendemic tick-borne bacterial genera in the southern Great Plains region. Questing behavior was observed using caged bioassays over 24-h periods throughout fall and spring, and field collections were conducted throughout the afternoon and evening in different locations across Oklahoma...

The members from Culex pipiens complex are the primary vector of various arboviruses including West Nile virus and Eastern equine encephalitis in the United States. Within Cx. pipiens complex, there are three biotypes that differ largely in habitat, bloodmeal preference, mating behavior, and overwintering strategy. The three biotypes are Cx. pipiens form molestus (F.) (Diptera: Culicidae), Cx. pipiens f. pipiens (L.) (Diptera: Culicidae), and Cx. pipiens quinquefasciatus (Diptera: Culicidae) (also known as Cx...

The sand fly fauna in Hipólito Yrigoyen, Argentina, a locality where cutaneous leishmaniasis cases occur, was surveyed with zones of higher abundance of sand flies correlated to vegetation cover estimated through normalized difference vegetation index (NDVI). Sand flies were collected with 10 CDC traps during six nights, from December 2009 to January 2010. A map was built of expected sand flies abundance in which levels of NDVI were categorized. In total, 1,392 Phlebotominae (Diptera: Psychodidae) specimens were collected, comprised of the following species: Nyssomyia neivai (Pinto 1926), Migonemyia migonei (França 1920), species of the cortelezzii complex (Brèthes 1923), Evandromyia sallesi (Galvão & Coutinho 1940), and Psathyromyia shannoni (Dyar 1929)...

Vector abundance plays a key role in transmission of mosquito-borne disease. In Hawaii, Aedes albopictus (Skuse) (Diptera: Culicidae), the Asian tiger mosquito, has been implicated in locally-transmitted dengue outbreaks, while Culex quinquefasciatus Say (Diptera: Culicidae), the southern house mosquito, is the primary vector of avian malaria, a wildlife disease that has contributed to declines and extinctions of native Hawaiian birds. Despite the importance of these introduced species to human and wildlife health, little is known about the local-scale drivers that shape mosquito abundance across lowland Hawaii, where forest, agricultural, and residential land uses are prevalent...

Biological control can assist in the management of disease vector mosquitoes. However, we urgently require the identification of novel and effective agents to aid population management strategies. Previously, predatory biocontrol of disease vector mosquito species has focused extensively on cyclopoid copepods, but prey size refuge effects have been identified as a hindrance to their predatory efficacy. Calanoid copepods have yet to be examined in the context of mosquito control, despite their high prevalence, diversity, and distribution...

Flies of the family Calliphoridae play a variety of ecological roles. They carry various pathogens and cause myiasis in humans and livestock, but they are useful to forensic entomology and in larval therapy. Mesembrinellidae flies, formerly classified in the family Calliphoridae, are good bioindicators of human interference in natural environments. In this study, we carried out an inventory of the Calliphoridae and Mesembrinellidae at four collecting sites within the Jardim Botânico do Rio de Janeiro. Eight traps were set, four in the arboretum (sites A and B), where the public is allowed to visit, and four at an Atlantic Forest fragment (sites C and D), open only to researchers...

Aldrichina grahami (Aldrich) (Diptera: Calliphoridae) is a forensically important species mainly found in Asia and is one of the first species to colonize a corpse in early spring and late autumn when the ambient temperature is slightly lower. In this study, A. grahami was collected from the Yangtze River Delta region and reared at seven constant temperatures ranging from 16 to 34°C to investigate the indices of development duration, accumulated degree hours, and larval body length. Using these results, we generated an isomorphen diagram, thermal summation model, and isomegalen diagram for A...

Seven populations of Simulium parahiyangum Takaoka & Sigit (Diptera: Simuliidae), a geographically widespread nominal species of black fly in Southeast Asia, were morphologically and molecularly studied. Three morphoforms based on male and pupal morphological features, and two primary lineages based on the COI gene sequence analysis were recognized. Morphoform 1 (lineage 1) from Sarawak, Malaysia, is identified as S. parahiyangum sensu stricto and morphoform 2 (lineage 2) from Thailand and Vietnam, and morphoform 3 (lineage 1) from Peninsular Malaysia are each regarded as distinct species, although morphoform 3 is partially homosequential for the COI gene with morphoform 1...

Culex quinquefasciatus Say (Diptera: Culicidae) is a mosquito species that has attracted a lot of attention from a medical and veterinary point of view; however, little is known about the frequency of L1014F mutations that have been found in the sodium channel gene, with this being a target for DDT and pyrethroid insecticides. The distribution and frequency of the L1014F mutation in Cx. quinquefasciatus populations was determined in rural and urban areas of Yucatan, Mexico from January 2015 to March 2016. Nine hundred fifty adult females out of 17,727 immature states were collected and analyzed in all sites sampled (n = 10)...

In the United States, the lone star tick, Amblyomma americanum (L.) (Acari: Ixodidae), is an aggressive southeastern species whose range has reportedly been steadily expanding northward. The number of A. americanum specimens submitted to the Tick Testing Laboratory (TTL) at the Connecticut Agricultural Experiment Station (CAES) increased by 58% from the period of 1996-2006 (n = 488) to 2007-2017 (n = 773), mainly from Fairfield County in the southwestern corner of the state. The greatest numbers of A. americanum submissions to the CAES-TTL were from the City of Norwalk and a few adjacent municipalities...

Aedes aegypti (L.) (Diptera: Culicidae) is a vector of viruses causing dengue, Zika, chikungunya, and yellow fever and subsequently pose a significant global threat to public health. While sampling live mosquitoes is useful for surveillance purposes, most traps targeting Aedes kill captured mosquitoes. The Biogents Sentinel (BGS) trap, the gold standard for capturing Ae. aegypti, is one such trap. In our study, we modified the BGS trap to increase the survival of captured Ae. aegypti by replacing the trap's catch bag with a catch pot that protects mosquitoes from desiccation by airflow...

Geographical regions have a major effect on the arrival times of different insect species on carrion. This means that data generated in one region should not be used to determine time of death in a different region. In the present study, we demonstrate the effect of geographical location on the diversity of carrion beetles in Saudi Arabia, whereas the mitochondrial cytochrome c oxidase subunit I (mtCOI) barcodes were used as a marker for molecular identification of the carrion beetles at a dry stage on sheep carrion...

Blacklegged ticks (Ixodes scapularis Say, Acari: Ixodidae) are the most commonly encountered and medically relevant tick species in New York State (NY) and have exhibited recent geographic range expansion. Forests and adjacent habitat are important determinants of I. scapularis density and may influence tick-borne pathogen prevalence. We examined how percent forest cover, dominant land cover type, and habitat type influenced I. scapularis nymph and adult density, and associated tick-borne pathogen prevalence, in an inland Lyme-emergent region of NY...

The primary aim of this study was to determine if the Asian tiger mosquito (Aedes albopictus (Skuse)) (Diptera: Culicidae), that vectors a number of arboviruses, is parasitized by water mites (Acari: Prostigmata: Parasitengonina: Hydrachnidiae). Larval water mite parasitism of adult mosquitoes has been shown to reduce mosquito fecundity and life span in the laboratory, and impact some populations in the field. Water mites have been considered for biocontrol purposes and used to age-grade mosquito populations...

The physical characteristics of a nematoceran fly that evokes the image of a mosquito of the genus Anopheles Meigen (Diptera: Culicidae) has existed since the genus was defined in the early part of the twentieth century. Is that image likely to change with the recent proposal to elevate four Neotropical subgenera to generic status based on relationships generated by phylogenetic analyses of mitochondrial protein-coding genes? Reasons for retaining the traditional concept of Anopheles, with its traditionally recognized subgenera, are presented...
